Visualization for non-optical remote sensing data

摘要:

对非光学遥感数据进行可视化处理有利于信息的提取和识别。伪彩色处理是非光学遥感图像增强和显示的常用方法,调色板的编码技术是非光学遥感图像伪彩色显示的关键。对照灰度编码方法,给出了非线性伪彩色编码方法和类JET伪彩色编码方法,并以干涉合成孔径声纳湖试数据处理为例,验证了这些方法的有效性。

Abstract:

Visualization of non-optical remote sensing data is in favor of extraction and recognition of information. Pseudo-color processing is commonly used in non-optical remote sensing image enhancing, in which coding of palette is the key. Contraposing gradation coding method, non-linear pseudo-color coding method and approximate JET pseudo-color coding method are put forward. Results from lake trials of interferometric synthetic aperture sonar (InSAS) indicate the validities of these methods.
